Castle Pinckney (Charleston, South Carolina)

Charleston · South Carolina · American Civil War

Quick BriefCastle Pinckney, a state-of-the-art masonry 'castle' fort completed in 1810 and designed by Jonathan Williams, became the first Federal military installation seized by force when South Carolina militia captured it on December 27, 1860—one of the opening acts of the Civil War. During the war it briefly held Union prisoners of war and served as an artillery position defending Charleston Harbor. The fort now stands in ruins on Shutes Folly island, accessible only by boat.

History & Significance

Castle Pinckney began construction in 1809 under the supervision of Jonathan Williams, designer of America's Second System of coastal fortifications. The innovative circular masonry design, modeled on European military theory, protected Charleston Harbor as one of three major Federal defenses alongside Forts Sumter and Moultrie.

Following South Carolina's secession on December 20, 1860, the small garrison under Lieutenant Richard K. Meade surrendered the fort to state militia on December 27, marking the first forcible seizure of a Federal military installation by a Southern state. After the Confederate bombardment of Fort Sumter in April 1861, the Charleston Zouave Cadets garrisoned Castle Pinckney and converted it into a military prison.

Between September and December 1861, the fort held 154 Union prisoners captured at the First Battle of Bull Run, though overcrowding required their transfer after only six weeks. Despite inadequate space, the prisoners were treated relatively well; contemporary photographs show them socializing with guards.

Confederate engineers subsequently reinforced the fort with earthen embankments and additional artillery for the defense of Charleston Harbor, where it remained until Union occupation in 1865. The fort itself never fired a hostile shot during its long service.

Portions of the brick walls were dismantled in 1890 to construct a harbor lighthouse. Castle Pinckney became a National Monument in 1924 before Congress abolished that designation in 1951, eventually transferring the island to the South Carolina Ports Authority.
